Just because personal information on criminal suspects in their teens or younger has been made available online doesn't mean it is proper for the mass media to publicize it, an expert said Friday.

The comment was made in criticism of the weekly Shukan Shincho, whose Thursday issue ran an article that contains the full name and photos of the 18-year-old who was arrested last week on suspicion of stabbing 13-year-old boy in Kawasaki to death.

The Japanese police do not disclose personal information on criminal suspects who are minors.
